To all whom t may concern:

Be it known lthat I, HARRY L. Bosmans, a citizen of the United States,and resident of theV city of St. Louis and State of Missouri, haveinvented certain new and usefulV Improvements in Knockdown CorrugatedPaper Boxes, of which the following is a specilication containing afull, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

My invention relates to certain new and useful improvements in knockdown corrugated paper boxes, and has forits primary object theconstruction of a corrugated p aper box which may be folded, providedwith a hinged lid attached thereto which may be folded out flat on thebody of the box for shipping purposes.

In the drawings,

Fig. 1 is a plan view of the box collapsed and the lid thereof flattenedout and superimposed upon the collapsed box.

Fig. 2 is an edge view of the same.

Fig. 3 is a front elevation of the box set up, ready for use.

Fig. 4 is a rear fragmental view illustrating the means of attaching thelid to the box. s

Fig. 5 is a fragmental transverse section through the lid andthe upperportion of the box.

Referring to the drawings,

6 indicates one side of the box and 7 indicates two of the bottom flaps.

In the construction of the body of the box there are four side walls,such as 6, the same being made out of a single piece of cardboard, andthe opposing ends of the piece of cardboard, being secured together bymeans of a strip of paper or fabric. The side walls when so constructedare capable of collapsing. The bottom flaps 7 (four in number) areformed integral with the side walls and between the adjacent ends of theiiaps, slots or cut away portions 8 are formed so as to permit the endsto be folded in wardly in the bottom when the device is set up for use.In setting up the box for use, two of the opposing end flaps are foldedfirst and between the other two end flaps, and then the outside end iapsare folded upon the first mentioned end flaps.I and then by means of astrip of paper or fabric, the outside end flaps are secured together andthe body of the box is set up for use, The sides and bottom of the boxare made of corrugated paper board and the cover or lid 9 is made out offiber cardboard. The lid 9 is provided with two side flaps 10 havingtheir rear corners cut away as at 11. 12 indicates the folding lines forthe side flaps 10. The side yiaps are provided with extensions 13 whichare adapted to .be folded on the transverse folding lines 111. 15indicates the front fla-p which is separated from the extensions 18 bymeans of slots 16. The flaps 13 are provided with studs 17 and the frontflaps 15 are provided with sockets 18 `adapted to receive said studs.The studs and sockets form' a detachable connection between theextensions 13 and the front lid flap 15. By means of this detachableconnection, the extensions may be detached from the 4flap 15 andthe lidfolded out flat, as illustrated in Fig. 1. When it is desired to set upthe lid for use, the'extensions 13 are folded under the iap 15 and thestuds are inserted in the sockets. In this form the lid is set up andready for use. The lid k9 is also provided with a rear flap 19 whichanswers as a hinge member. Said hinge flap is placed along the rear sideof the box on the outside and is secured thereto by means of staples 20.

lt will be observed from'the foregoing description that the body of thebox may be knocked down or collapsed, and that the lid may be alsoknocked down and collapsed and folded on the collapsed box asillustrated in Fig. 1, and by means of such construction a greatamountof space is saved in packing andshipping, and further, that the box maybe readily set up for use by unskilled labor.

Having fully described my invention, what I claim is:

1. A. knock down corrugated paper box haviiio` collapsible side wallsand collapsible bottom flaps, a lid hingedly secured to the. top edge ofone of said walls, said lid having a pair of collapsible side flapsprovided with collapsible extensions, an intermediate collapsible flapspaced apart from said extensions, a fastener secured to each extension,and a fastener secured to each end of the intermediate "iiap adapted tobe readily engaged with and disengaged from the fasteners carried by theextensions for holding the lid in made up form.

2. Ar knock down corrugated paper box having collapsible side wallsformed from a single piece of material, a pair of opposed {iaps adaptedto be folded on the inside of the box and a pair of o posed flapsadapted to be folded upon the l rst mentioned iaps and mountedtransversely with the first mentioned laps, said lpairs of aps adaptedto form the bottom of the box when so folded, a collapsible lid hingedlysecured to the piece ofmeterial out of which `the body of the box is`formed, saidlid having opposed collapsible side flaps provided withcollapsible extensions7 a collapsible intermediate Hap spaced apart fromthe extensions, and a readily attachable and detachable connectionbetween said extensions and the intermediate flap whereby the lid may bereadily assembled and collapsed. x

In testimony whereof, I have signed my name to this specification.
